Transitioning from rich to lean reinforcement as a form of error correction

Discrete trial instruction (DTI) is a ubiquitous tool used by practitioners in early intervention programs. A common approach to correcting errors during DTI involves providing a single prompt of the target response when a mistake is made (i.e., single-response repetition). Modifications to the single-response repetition approach have been developed to improve acquisition; however, these modifications are often aversive techniques (e.g., increased effort, response cost) and may not be preferred by the children or considered socially acceptable by caregivers. We conducted this study to evaluate the use of a transition from rich to lean reinforcement as a form of error correction. We compared the rich–lean condition to the single-response repetition approach during DTI for 4 boys diagnosed with autism. The rich–lean condition was (a) more efficient in improving accuracy in 6 out of 9 tasks, (b) more preferred by all participants, and (c) socially validated by caregivers.     

Lost in the move? Secondary task performance impairs tactile change detection on the body

Change blindness, the surprising inability of people to detect significant changes between consecutively-presented visual displays, has recently been shown to affect tactile perception as well. Visual change blindness has been observed during saccades and eye blinks, conditions under which people’s awareness of visual information is temporarily suppressed. In the present study, we demonstrate change blindness for suprathreshold tactile stimuli resulting from the execution of a secondary task requiring bodily movement. In Experiment 1, the ability of participants to detect changes between two sequentially-presented vibrotactile patterns delivered on their arms and legs was compared while they performed a secondary task consisting of either the execution of a movement with the right arm toward a visual target or the verbal identification of the target side. The results demonstrated that a motor response gave rise to the largest drop in perceptual sensitivity (as measured by changes in d′) in detecting changes to the tactile display. In Experiment 2, we replicated these results under conditions in which the participants had to detect tactile changes while turning a steering wheel instead. These findings are discussed in terms of the role played by bodily movements, sensory suppression, and higher order information processing in modulating people’s awareness of tactile information across the body surface.     

What makes for a good break? A diary study on recovery experiences during lunch break

This study investigated the role of four recovery experiences during lunch break for employees’ afternoon well‐being. We hypothesized that lunch‐break recovery experiences (psychological detachment, relaxation, control, and relatedness) reduce afternoon exhaustion and enhance afternoon work engagement via replenished personal resources (i.e., state of being recovered immediately after break and subsequent self‐efficacy regarding the upcoming tasks in the afternoon). One hundred and nine employees provided daily survey data three times a day (i.e., start of work, after lunch break, end of work) over a period of two workweeks. Multilevel path analysis showed that relaxation, control, and relatedness during lunch break negatively predicted afternoon exhaustion and positively predicted afternoon work engagement via state of being recovered. For relaxation and relatedness, we additionally found positive serial indirect effects on afternoon work engagement via state of being recovered and self‐efficacy. Psychological detachment was not related to personal resources and afternoon well‐being. This study demonstrates that experiencing control over lunch break and using the lunch break to relax and to relate to others are indirectly associated with improved afternoon well‐being via replenished personal resources.

Practitioner points

• Relaxation, control, and relatedness constitute lunch‐break recovery experiences that indirectly foster feeling confident, replenished, and engaged in the afternoon.
• Employees should strive to spend their lunch breaks in ways that help them feel relaxed, related, and in control.
• Organizations should provide their employees with sufficient break control and offer environments that facilitate relaxation and socializing during lunch break.

     

Private Announcements on Topological Spaces

In this work, we present a multi-agent logic of knowledge and change of knowledge interpreted on topological structures. Our dynamics are of the so-called semi-private character where a group G of agents is informed of some piece of information \(\varphi \), while all the other agents observe that group G is informed, but are uncertain whether the information provided is \(\varphi \) or \(\lnot \varphi \). This article follows up on our prior work (van Ditmarsch et al. in Proceedings of the 15th TARK. pp 95-102, 2015) where the dynamics were public events. We provide a complete axiomatization of our logic, and give two detailed examples of situations with agents learning information through semi-private announcements.     

Transformation of Adolescent Peer Relations in the Social Media Context: Part 1—A Theoretical Framework and Application to Dyadic Peer Relationships

Investigators have long recognized that adolescents’ peer experiences provide a crucial context for the acquisition of developmental competencies, as well as potential risks for a range of adjustment difficulties. However, recent years have seen an exponential increase in adolescents’ adoption of social media tools, fundamentally reshaping the landscape of adolescent peer interactions. Although research has begun to examine social media use among adolescents, researchers have lacked a unifying framework for understanding the impact of social media on adolescents’ peer experiences. This paper represents Part 1 of a two-part theoretical review, in which we offer a transformation framework to integrate interdisciplinary social media scholarship and guide future work on social media use and peer relations from a theory-driven perspective. We draw on prior conceptualizations of social media as a distinct interpersonal context and apply this understanding to adolescents’ peer experiences, outlining features of social media with particular relevance to adolescent peer relations. We argue that social media transforms adolescent peer relationships in five key ways: by changing the frequency or immediacy of experiences, amplifying experiences and demands, altering the qualitative nature of interactions, facilitating new opportunities for compensatory behaviors, and creating entirely novel behaviors. We offer an illustration of the transformation framework applied to adolescents’ dyadic friendship processes (i.e., experiences typically occurring between two individuals), reviewing existing evidence and offering theoretical implications. Overall, the transformation framework represents a departure from the prevailing approaches of prior peer relations work and a new model for understanding peer relations in the social media context.     

Expanding Knowledge of Parental Involvement in Children's Secondary Education: Connections with High School Seniors' Academic Success

This paper analyzes data from the parent and student components of the National Educational Longitudinal Study of 1988 to investigate family educational involvement in secondary education. It examines connections between parental involvement practices and the educational outcomes of high school seniors. Utilizing multiple involvement indicators for the 8th and 12th grades, the study concludes that the nature of relationships between parental involvement and 12th grade educational outcomes depends on the type of parental practices and educational outcomes considered. Parental involvement indicators are not associated with achievement growth between the 8th and 12th grades. However, a number of parental involvement indicators are associated with seniors' enrollment in an academic high school program and with their coursework in core academic subjects. High levels of educational expectations, consistent encouragement, and actions that enhance the learning opportunities of children are the family practices that are positively associated with the above educational experiences of high school seniors. The relationships between parental involvement and educational outcomes exist regardless of students' socioeconomic or race/ethnic background and regardless of whether parental practices are measured in the middle grades or in high school.
